N‐Doping Activated Presodiation Enhances Sodium‐Ion Provision in Hard Carbon Anodes
Advanced Science, EarlyView.Introducing pyrrolic‐N sites enables efficient presodiation and stronger PF6− capture, thus pre ‐ forming a robust inorganic‐rich SEI layer in hard carbon anodes. ABSTRACT Hard carbon (HC) is considered the most promising anode material for commercial sodium‐ion batteries (SIBs), yet it still faces critical challenges such as low initial Coulombic ...

Transient stimulated Raman scattering spectroscopy and imaging
Light: Science & ApplicationsStimulated Raman scattering (SRS) has been developed as an essential quantitative contrast for chemical imaging in recent years. However, while spectral lines near the natural linewidth limit can be routinely achieved by state-of-the-art spontaneous ...

Advanced Science, EarlyView.The weakly‐solvating TFMSPyr electrolyte tailors the Li+ solvation structure by suppressing solvent coordination and promoting anion‐dominated solvation. This unique solvation environment induces preferential anion decomposition at electrode interfaces, forming robust inorganic rich S/CEI.

Observation of Excitonic Instability in a Monolayer Ta2NiSe5 With Strain Disorder
Advanced Science, EarlyView.Monolayer Ta2${\rm Ta}_2$NiSe5${\rm NiSe}_5$ sustains an excitonic insulating phase up to 190 K, with Raman signatures of gap opening and critical excitonic fluctuations. Thickness‐independent large gap ratios highlight strong exciton‐phonon coupling, while substrate‐induced strain disorder depresses Tc, establishing monolayer Ta2${\rm Ta}_2$NiSe5${\rm

Boosted decision trees for non-resonant background removal in hyperspectral CARS microscopy
JPhys PhotonicsCoherent anti-Stokes Raman scattering (CARS) is a nonlinear optical process used for spectroscopy and label-free chemical imaging. CARS signals can be orders of magnitude stronger than those of its incoherent counterpart, spontaneous Raman scattering ...

Spontaneous and stimulated Raman scattering in planar silicon waveguides
, 2011 Raman scattering in planar silicon on insulator (SOI) waveguides with 2 μm width, 220 nm height and 2 cm length is investigated. A cw Nd:YAP laser at 1340.6 nm with 7 GHz FWHM spectral width is used as the pump source.
